U.S. Deputy Defense Secretary Paul Wolfowitz says the United States will respond to terrorist attacks in New York and Washington with a sustained military campaign.

"One thing is clear, is that you don't do it with just a single military strike, no matter how dramatic," Wolfowitz said September 13 at a noon Pentagon briefing. "You don't do it with just military forces alone, you do it with the full resources of the U.S. government.

"We're going to keep after these people and the people who support them until this stops. And it has to be treated that way."

Wolfowitz took note that President Bush on September 12 asked Congress for a $20,000 million emergency supplemental appropriation for 2001 to help pay for military, emergency and civil support operations, and for a mission to combat global terrorism. The request comes in the wake of terrorist strikes at the World Trade Center in New York and the Pentagon in the Washington, D.C., area carried out by suicide teams of hijackers, and the crash of a hijacked commercial jetliner 130 kilometers southeast of Pittsburgh, Pennsylvania.

"It's government-wide, it's not just the Defense Department" that is seeking these emergency funds, he said. "But obviously, a very great portion of those needs are to prepare our armed forces for whatever the president may ask them to do."

Wolfowitz said the anti-terrorism campaign will be multifaceted.

"These people try to hide, but they won't be able to hide forever," he said. "They think their harbors are safe, but they won't be safe forever. I think one has to say it's not just simply a matter of capturing people and holding them accountable, but removing the sanctuaries, removing the support systems, ending states who sponsor terrorism."

That, he said, is why the anti-terrorism campaign has to be broad and sustained. "It's not going to stop if a few criminals are taken care of," he said.
